7th and 8th grades
Week of June 8
You can do any 8th Grade Math IXL, any 8th Grade Math Khan Academy assignment, or our Jlab version of "Are You Smarter Than A Fifth Grader?" 
"Are You Smarter Than A Fifth Grader?" was a game show that was popular from 2007 until 2015.  The game challenged players to answer fifth grade level questions correctly.  Play a version of "Are You Smarter Than A Fifth Grader?"  Go to https://education.jlab.org/solquiz/.  Start at second grade.  Choose 5 or more questions and see how you do.  Continue through the grade levels to see how far you can go.  If you add your name, you will have the option to e-mail me your results.  Doing this activity is optional.  E-mailing your results is optional.
